Commands

This CLI tool provides an easy way to manage Talos powered Kubernetes clusters on the Hetzner Cloud. Bootstrapping a new cluster performs the following steps:

• Create private network 10.0.0.0/16 for inter-node communication
• Create placement group to ensure nodes to not run on the same physical machine
• Create load balancer to access the controlplane nodes Kubernetes API server (port 6443) or Talos API server (port 50000)
• Create firewall rules to block access to nodes from outside of the private network
• Create first controlplane node
• Install Hetzner Cloud Controller Manger
• Install Hetzner CSI Driver
